python--列表，元组，字符串互相转换

>>> s = "xxxxx" >>> list(s) ['x', 'x', 'x', 'x', 'x'] >>> tuple(s) ('x', 'x', 'x', 'x', 'x') >>> tuple(list(s)) ('x', 'x', 'x', 'x', 'x') >>> list(tuple(s)) ['x', 'x', 'x', 'x', 'x'] 列表和元组转换为字符串则必须依靠join函数 >>> "".join(tuple(s)) 'xxxxx' >>> "".join(list(s)) 'xxxxx' >>> str(tuple(s)) "('x', 'x', 'x', 'x', 'x')" >>>
